Planes Velocity Problem

Kyle is flying a plane due north at 230 km/h as a wind carries it due east at 56 km/h. Find the magnitude and direction of the plane's resultant velocity analytically.
236.7 km/h (magnitude)
° (direction)

2. Relevant equations

Tan=opp/adj

3. The attempt at a solution

This should be straightfoward but i guess not?
I tried:
tan^-1 (56/230)=13.7 degrees

Cant seem to figure out why this isnt working it should be straightfoward
